The victim has been identified as Samuel Paty, 47, a history and geography teacher.
Paty’s body was found in Éragny-sur-Oise, north-west of the French capital, according to the French national counterterrorism prosecutor’s office. The prosecutor’s office confirmed that the attacker was killed by police in the same neighborhood.
The prosecution told CNN that Paty was a teacher in a high school in the Conflans-Sainte-Honorine region.
French President Emmanuel Macron said Paty was “killed for teaching students about freedom of speech, the freedom to believe and not to believe”.
Macron, speaking at the scene, said the teacher was “the victim of an Islamist attack”.
Police have provided a few more details about the perpetrator, victim or incident. The anti-terrorism prosecution, which has taken over the investigation into the attack, has not spoken publicly of a motive.
Macron will visit the city following an emergency meeting at the Interior Ministry, the Elysee Palace told CNN.
The Minister of the Interior Gerald Darmamin declared on Twitter that he “was kept directly informed” of the situation “from the crisis room (which he) had opened, in liaison with the President of the Republic and the Prime Minister “.
Education Minister Jean-Michel Blanquer called the attack a “despicable murder of one of his servants, a teacher,” and said his thoughts were with the victim’s family.
